The Riverhead school board plans to put a special proposition on the May 16 ballot asking voters to create a $7.5 million repair reserve, a fund similar to the $5 million in reserves approved in 2011 and 2015.

The Riverhead School District unveiled the second portion of its 2017-18 budget plan at Tuesday night’s meeting, outlining changes in spending for facilities, security, transportation and curriculum and instruction.

Local school districts are preparing for another tight budget season this year, with minimal state aid increases projected in Gov. Andrew Cuomo’s tentative spending plan and a cap of less than 2 percent on tax levy growth.
